Module execution 

Execution primitives for vectorized query processing.

This module provides the core data structures for vectorized execution:

• chunk - DataChunk for batched tuple processing
• vector - ValueVector for columnar storage
• selection - SelectionVector for filtering
• operators - Physical operators (scan, filter, project, join)
• pipeline - Push-based execution pipeline
• sink - Common sink implementations
• memory - Memory-aware execution context
• parallel - Morsel-driven parallel execution
• spill - Transparent spilling for out-of-core processing
